"Nothing I'm wearing has a negative impact," Mraz explained, showing off his slate blue Eco Tux, crafted by Simon Carter. "The suit is made of recycled water bottles and wool, and the tie is made from recycled cassette tapes, so you can listen to the past nominees of the Grammys," he joked.

Mraz topped the eco-friendly outfit off with fair-trade shoes from Guatemala. "You choose what you want to do, what you want to wear," he said. "It’s all about making conscious choices."

Mraz is nominated for best male pop vocal performance for the single, "Make it Mine," and for best pop collaboration with vocals for the song "Lucky" with Colbie Caillat, one of the singers Mraz said he's most looking forward to seeing. "It’s two years later that we wrote that song," he said, "and here we are celebrating it."

@ RickyLee: 100 of the 109 Grammys were given out during the pre-show, as opposed to the telecast, including Pop Instrumental Performance (Bela Fleck), Rock Instrumental Performance (Jeff Beck), and Country Instrumental Performance (Steve Wariner).
